The determination of a toxic level for digoxin is essential for safe pharmacological management, especially in patients with heart conditions like atrial fibrillation or heart failure. Digoxin has a narrow therapeutic index, which means the range between effective and toxic doses is small.

A digoxin level greater than 2.0 ng/mL is considered toxic and indicates that the patient is at increased risk for digoxin toxicity, which can lead to serious consequences such as cardiac arrhythmias, gastrointestinal symptoms, and neurological changes. Monitoring serum levels of digoxin is crucial in managing dosage and preventing toxicity.

Maintaining levels below this threshold is key to ensuring therapeutic effectiveness while minimizing harmful side effects. Understanding these levels helps guide nursing interventions, patient education, and monitoring strategies in providing holistic care for individuals on digoxin therapy.
